I can't see any content from https://lemmy.ca/c/progressivepolitics@lemmy.world even though the community is right there https://lemmy.world/c/progressivepolitics

Instead I see a "Error! There was an error on the server" message.

As far as I can tell from my modlog and the modlog of the community I haven't been banned.

I can see other lemmy.world communities, like for example https://lemmy.ca/c/world@lemmy.world so I don't think some kind of block at the instance level has happened.

What is going on?
